CPMT090308 NS9530 Tungaloy indexable insert for turning — rhombic, 0.8 mm radius

The CPMT090308 NS9530 is an ISO‑standard rhombic indexable insert designed for external and internal turning, optimised as a finishing grade for steel with a sharp uncoated cutting edge.

• ISO‑standard rhombic shape
• Sharp edge for finishing operations
• Uncoated cermet grade NS9530
• Cylindrical hole with countersink 40°–60°

High‑quality finishing with low cutting forces

The insert is specified as an uncoated cermet finishing grade (NS9530) and is engineered to deliver a high surface finish with low cutting forces. Cermet grades combine ceramic and metallic properties to provide a very sharp, wear‑resistant edge that produces less built‑up edge and finer surfaces compared with conventional carbides when used for light to moderate finishing passes. This makes the component particularly suited to continuous cuts and small depths of cut, where smoother surface outcomes reduce downstream grinding and polishing effort and therefore improve overall process efficiency.

Consistent fit and simple integration into existing tool systems

As an ISO‑standard insert in the CPMT form series, the component ensures reliable compatibility with matched holders and tool posts. Key geometry features — the rhombic shape, 11° clearance angle, 80° included angle, 0.8 mm corner radius and a 3.18 mm plate thickness — allow stable seating and repeatable positioning. The insert is supplied with a cylindrical hole and a single‑sided countersink (40°–60°) for secure fastening; these details reduce setup variability and help maintain consistent cutting geometry across index changes. The precise fit parameters mean fewer trials during tool changeover and lower downtime in production.

Efficiency and stability for finishing cycles

The single‑sided chipbreaker and the sharp cermet composition are tuned for productive finishing of steel, offering controlled chip formation and predictable cutting behaviour. This contributes to steady process performance during extended runs and supports a positive cost‑benefit through reduced rework and stable machining quality. Selecting the correct chipbreaker and grade for the specific steel alloy and cutting conditions helps to maximise productivity while preserving machine resources. For operations prioritising surface quality and minimal cutting forces, the insert represents a practical choice that aligns technical reliability with economic performance.

FAQ

What materials is this insert suitable for? The CPMT090308 NS9530 is formulated as a finishing grade for steel and is intended primarily for fine turning operations on steel components.

Is the insert coated or uncoated? This Tungaloy indexable insert is an uncoated cermet grade (NS9530), chosen for its sharp cutting edge and ability to produce superior surface finishes.

How is the insert fixed to the toolholder? The insert is supplied with a cylindrical hole and a single‑sided countersink (40°–60°); it is secured to a compatible ISO holder using the appropriate clamp or screw in accordance with the tool system specification.

What does the 0.8 mm corner radius mean for machining? A 0.8 mm corner radius provides a balance between edge strength and surface finish; it reduces the tendency to chatter compared with a razor edge while still delivering a fine surface on finishing passes.

Can this insert be used for internal turning? Yes, the ISO‑standard rhombic form and the NS9530 finishing grade allow the CPMT090308 to be used for both external and internal turning where the geometry and holder clearance are suitable.
